Reference Management and Bibliography Software for Mac OS X

The free introductory version of Bookends will never timeout and is fully functional except for a 50 reference limit per library. To run it you will need a Macintosh running Mac OS X 10.7 (Lion) or later. To activate the feature that allows you to enter unlimited references, please fill out the secure order form or contact Sonny Software to buy Bookends and receive your registration code.
